Everything in one calm place
Cocoon fuses the daily log and the journal — the tracker that also remembers — with trends, growth, sharing and a full export. Here's the whole picture.
Log in seconds, one-handed
Designed for the blur of the first year — start a timer or repeat a feed in a tap, half-asleep.
- Breastfeeding with left/right timers — and the side you fed last, front and centre
- Bottle feeds and pump sessions, with quick repeat
- Nappies / diapers — wet or dirty, one tap
- Sleep timers and naps that carry across midnight, with settle & held-to-sleep notes
- A running feed or sleep timer stays on your lock screen, so you never lose track
- Solids, growth, health & medications, and milestones
A journal that grows with them
The memories you don't want to lose, held right alongside the data.
- A private photo and video journal of everyday moments
- Fullscreen photo lightbox and day, week and month views
- Daily prompts, a scrapbook, and “on this day” memories
- Search to find any moment in an instant
The worrying little things, handled
Medicine timing, a temperature, a glass of wine on a hard day — made calm and clear.
- Medicines with dose reminders and a clear “hours since the last dose” countdown
- Temperatures and symptoms, logged and ready to show your GP
- FeedSafe: an estimate of when alcohol has likely cleared your breast milk — based on your drinks, weight and time, to inform your judgement, never medical advice
- Never a diagnosis — Cocoon gives you context and gentle prompts, not medical advice
Patterns, gently surfaced
The reason to keep logging — clear, transparent insight that never pretends to be a diagnosis.
- Sleep, feeding rhythm and wake-window trends
- Growth percentiles on WHO and CDC charts
- A milk stash tracker for your freezer supply
- CDC milestones and gentle, evidence-based guides
- An assistant that explains your own logged data in plain language
One family, always in sync
Share once; everyone stays current — even with no signal.
- Invite your partner, a grandparent or a nanny once
- Everyone shares the same live, up-to-date log
- Offline-first — works on a walk, a plane, or at 3am
- Syncs automatically when you're back online
Yours to keep — no lock-in
Your memories should never be held hostage.
- Export every log, measurement and journal entry — plus all photos and videos — in one file
- Restore on any device, anytime: a true backup, not a teaser
- Import from Huckleberry, Baby Daybook, Cubtale, Nara Baby, Baby Connect, Day One, Apple Journal and more
Built to earn your trust
A baby app holds some of the most sensitive data there is. We treat it that way.
Row-level security
Only caregivers you invite can ever see your child's records.
Encrypted in transit & at rest
Your data is encrypted on the wire and in storage, and never sold or shared with advertisers.
Offline-first
Everything is saved on your device and works with no connection.
No ads, ever
Cocoon shows no ads and never sells your data. Your child's logs, photos and journal are never used for advertising.
Full export
Leave whenever you like and take the whole keepsake — data and media — with you.
Not a medical device
Cocoon is for observation and context — information for your doctor, never a diagnosis.
Track the days you'll forget.
Keep the ones you won't.
Cocoon is free, offline-first and ad-free. In private beta on Android now — iPhone is on the way.
